black diamond

I just bough 2 bag of this stuff.
Can someone tell me what's the stuff in the pic is?
Will it be safe with bottom feeder?
It is breakable and just wanna make sure its safe since one did poke into my skin
Every bag has those in there or is t just my?

I just bought 50lbs a few days ago and I have the same stuff in mine. I've read other threads where people found this and went with BD anyhow without problems. I'm just hoping that I don't run into any real issues with the stuff.
